GRAIN-BEARDER.

To all whom it may concern class of preparatory grain-handling inachines, known in the art as earders, the primary function of which, as the name implies, is to tear or break off the beards of such grains as barley and rice, or to so treat or act upon any grains, as, for example, to break the straw joints, smut balls, etc., as to reduce them to condition to enable the elevators, separators, scourers and the like to properly handle them; or to clip oats, or to separate into individuals a mass o grain clinging together after a bran scouring operation.

Although these machines may be applied to such various uses, their special application is the breaking of beards from barley and rice, and as they are known as barley bearders, I shall herein, for the sake of simplicity refer to my invention, and describe its use in terms of barley.

Barley bearders comprise an elongated drum horizontally disposed, having in'its top, near one end, a feed hopper, and in its other end a discharge gate.

Into the drum from each side project radially a line of spaced fixed spikes. In the ends or heads of the drum is mounted a shaft, which is rotated by means of power applied to a pulley on the shaft, said shaft extending through the drum in the axis thereof. The shaft, within the drum, carries a series of spaced and staggered spikes which play between the fixed spikes carried by the drum. The fixed and the revolving spikes cooperate to tear or break off the beards from the barley, and both beards and barley are delivered from the discharge gate, to be subsequently conveniently separated.

In common practice the drum of the bearder comprises two heads, a longitudinally divided sectional peripheral jacket seated in grooves in the heads, and longitu- Specification of Letters Patent.

dinal bolts tying the heads together and holding the jacket in its seat. In order to obtain access to the interior of the drum, for any purpose, it is necessary to take out the tie-bolts, and remove the heads, in order to separate the sections of the jacket. This practically requires the dismemberment of the machine, and as the rotating spike-shaft is mounted in the heads, this member of the machine is also ail'ected and its adjustment disturbed.

To overcome this difiiculty of gaining access to the interior of the machine, is the objectoi my invention, and to this end my invention consists in a novel construction of the drum which permits the ready removal and replacement of the jacket or any of its sections without disturbing the heads and Fig. 8 is an end view from the line 3-3 I of Fig. 2,'looking in the direction of the arrows. Fig. l is a cross section on the linedl of rig The headsl of the drum are cast with feet 2, the upper portions of the latter being formed with angle-shoulders 3. Upon the shoulders 3 are bolted the angle-tie-bars 4 which extend between and connect the heads rigidly together. There is one of these tiebars 4 on each side. 5 is the jacket. This comprises a plurality of sections, here shown as a top or cover section and a bottom section; The jacket may be of sheet iron or'of wire cloth, or in some cases of both; sheet iron being herein indicated.

The heads 1 are cast with an annular rabbet 1', Fig. 2, on their inner faces at their rims, and upon these rabbets the ends of the jacket sections lie. They are held to their seats by a plurality of semicircular straps 6, here shown as comprising three pairs, one member of each pair embracing the top or cover section of the jacketand the other member embracing the bottom section. The

ends of the upper straps are bent outwardly over the vertical. leg of the angle-tie bars 4 and lie. upon the upper surface of the horizontal leg of said bars, while the ends of the lower straps lie up against the under surface of said horizontal legs. These ends,

above and below, are secured to said horizontal legs bybolts 7.

8 are fixed splkes whichproject radially into the drum. These are formed with shanks 9 which pass outwardly through the vertical legs of the angle tie-bars 4 and i receive nuts 10 by which they areheldt fastening to be bent inwardly, as seen in Fig. .4, thereby forming groove seats in which the.

spikes carried by said shaft.

11 are reinforcing guide-plates fitted upon the shanks 9 of the spikes 8, and lying along and tight-up against the inner surface of the vertical legs of the angle tie-bars 4a These plates 11 have sufficient width tov enable them, both above and below their line of jacket has a feed hopper 16,- a-nd one of the heads 1 has a discharge gate 17-Fig. '3; .It will now beseen that to gain access to the interior of the machine, all that need be done is to take out the bolts 7 and remove the straps 6. The jacket, or either section of it, may then be lifted or dropped from its seat on the rabbets 1' of the heads andfrom its groove seats between the: guide plates 11 and the tie-bars at; and this removal doesnot affect, in any way, the remainder of the machine, as the heads are rigidly" connected by the tie-bars and the spike-shaft is not disturbed.

Iclaim:- V I '1. A ain-bearder comprising spaced heads having ra'bbet-shoulders; tie-plates J rigidly connecting said heads; a sectional peripheral 'j a'cket extending between and rest ing onthe rabbet-shoulders of the heads;

straps embracing the jacket-and detachably connected with the tie-plates;-spikes carried by and extending from the tie-plates into the space incl'osed'by the jacket; a rotatable shaft mounted in the heads, and passing through said space in the axis thereof; and

2. A grain-bearder comprising spaced r heads havingrabbetshoulders; tie-plates rigidly connecting said heads; a sectional peripheral jacket extending between and resting on the vrabbet-shoulders of the heads;

straps embracing the jacket and detachably 7 connected with the tie-plates; spikes carried by and extending from the tie-plates into the space inclosed by the jacket; guide plates secured by said spikes to the inner faces of the'tie plates and spaced therefromto form groove seats for the side edges of the jacket sections; a rotatable shaft mounted in the heads and passing through-the space inclosed by the jacket in the axis thereof; and spikes carried by said shaft.

8. A grain bearder comprising spaced heads having rabbet-shoulders, said heads being formed with foot members provided with angle-shoulders; angle tie-plates secured upon said angle-shoulders and rigidly connecting said heads; a longitudinally divided sectional peripheral jacket extending between and resting on the rabbet shoulders of the heads; a pair of straps embracing the sections of said jacket, above and below, the

ends of said straps being bolted to the horizontal leg of the angle tie plates; spikescarried by the vertical legs of said tie-plates and extending therefrom into the space inclosed by the jacket; a rotatable shaft mounted in the heads and passing through said space in the axis thereof; and spikes carried by said shaft. a

4. A grain-bearder comprising spaced heads having rabbet-shoulders, said heads being formed with foot members provided with angle-shoulders; angle-.tie-plates se-.

cured upon said angle-shoulders and rigidly connecting said heads; a longitudinally divided sectional peripheral jacket extending between and resting on therabbet shoulders of the heads; a pair of straps embracing the. sections of said jacket, above and below, the 1 endsof said straps being bolted tov the horizontal leg of the angle tie plates: snikes'carried by the vertical legs of said tie-plates and entendingtherefrom into thespace in: closed by Y the jacket; a rotatable shaft said space in the axis thereof; spikes carried by said shaft; and guide plates secured to the inner faces of the vertical legs of the tie plates by the spikes carried by said legs, said plates'being spaced from said inner faces to form groove seats for the side edges of the acket sections.

in testimony whereof I. have signed my name to this specification.
